How to Get Lung Cancer Without Smoking

Most of articles explain that smoking is one of the influential factors of lung cancer. Do you know that other factors cause lung cancer? In fact, non-smokers and non-passive smokers still vulnerability toward lung cancer. Therefore, commonly there are two factors that cause lung cancer without smoking as follows:

1. Asbestos Exposure

Exposure to asbestos is another well-known cause of lung cancer and mesothelioma – cancer of the pleural lining of the lungs. Asbestos was widely used in construction and everyday products in the late 1800s through the 1960s. Asbestos separates into fine silica fibers that become trapped in the tissues of the lungs. Mesothelioma is inextricably linked to asbestos exposure. There are no reported cases of mesothelioma in people who were not exposed to asbestos either in the workplace or through their environment. A non-smoker who was exposed to asbestos has a five times greater risk of developing lung cancer than a non-smoker who was not exposed. Smoking increases the risk dramatically – a smoker who was exposed to asbestos has a risk of developing lung cancer that is 50 to 90 times greater than that of a non-smoker.

2. Radon Gas

It is estimated that about 12% of lung cancer deaths can be attributed to radon gas, a colorless, odorless gas that is a natural byproduct of the decay of uranium. The U.S. Environmental Protection Agency estimates that as many as 15% of homes in the United States have unsafe levels of radon gas, which will account for 15,000 to 22,000 deaths from lung cancer annually.

Scientists estimate that as many as 1% of all lung cancer deaths are attributable to air pollution. They believe that prolonged exposure to very polluted air can raise the lung cancer risks of developing lung cancer without smoking.
